Chemical Properties and Tests

Platin ist niemals rein, immer mit Eisen (4-21%, bei > 11% bezeichnet man es als Eisen-oder Ferroplatin)in Verbindung. Weiterhin können Iridium (bis 7%, Iridiumplatin), Palladium (< 1%-7% Palladiumplatin), Rhodium (<1%-5% Rhodiumplatin), Nickel (gelegentlich einige Prozent, Nickelplatin)und Kupfer u.a. vorhanden sein.

Preface

Generation conditions

Primär in ultrabasischen Gesteinen (Dunit, Peridotit, Serpentinit) als junge (hydrothermale) Nachphase. Durch Zerstörung der primären Lagerstätten Anreicherung in Platinseifen.

Name from

Vom spanischen "platina", Verniedlichung von "plata", Silber.
